Electroluminescent display panel with enlarged active display areas

Abstract: An improved electroluminescent display panel having an X-Y array of display elements upon a planar insulating substrate Integral thin film transistor circuit elements and drive signal buses are interconnected on the panel with individual electroluminescent electrodes covering a large area of the panel to increase the active display area The electroluminescent electrode is a multilevel electrode with a first level portion disposed on the insulated substrate, a second level electrode portion disposed over an insulative polymerized layer which covers the thin film circuit areas and the drive signal buses, and a connecting electrode portion which extends between the first and second level electrode portions

Portable programmer-reader unit for programmable time registering electric energy meters

Abstract: A portable programmer-reader unit for programmable time registering AC electric energy meters utilizing replaceable program control data includes plural memory locations for programming, time and date synchronization, readout, and monitoring of the coded values of identical data items included in the meter program control data. A visual display provides numerical readouts of the data items including meter readings for different time categories of electric energy measurement by said meter and indication of error condtions. Manual control and a data entry inputs control meter data communication, readouts of the visual display and modification of the data items stored in the programmer-reader unit for programming the meter. Power conserving logic circuits extend field use while operating with a battery power supply.

Method and apparatus for improving the servicing of an elevator system

Abstract: Methods and apparatus for improving the servicing of an elevator system based upon the actual usage of its many functions. The usage of predetermined elevator system functions is monitored and data is collected relative thereto. Threshold and limit parameters are provided for the monitored functions, which parameters are periodically compared with the usage data. The reaching of a usage threshold parameter by a monitored function results in predetermined associated maintenance services being added to a maintenance due list. When a monitored function reaches its associated limit parameter, a need for scheduled elevator preventive maintenance is indicated for all of the maintenance services on the maintenance due list.
